Water leak

I have a Karcher 420MH model and seem to have a water leak around the cylinder head area. Is this a common fault and can it be fixed?

  • Had the same problem with a 380. Tried to repair but the pressure is too great( shows how good the Karcher is). Bought a new head of espares, stripped and fitted in about 35 minutes. By Anonymous - N. Yorkshire - 16 July 2012
